OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 365,547, date'd Jne'28, 1887.

Application filed November 4, 1886. Serial No. 217,962. (No model.)

To all whom, it may concern:

Be it known that I, JOHN M. SMYTH, of Windsor, in the countyrof Essex and Province of Ontario, Canada, have invented new and useful Improvements in Oil-Cups; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, which forms a part of this specification.

This invention relates to certain new and useful improvements in oil-cups. A

The invention consists in the peculiarV confully hereinafter described. In the accompanying drawing,which forms shown in central vertical section, wherein- A represents a cylindrical cup terminating in a central plug, B, which is threaded, as shown,on its outer surface, and it has an orifice, c, through such stud, the lower end of C is another cylinder fitting closelywithin the cup A, and near its upper end its walls are provided with perforations c. The top of this cylinder C is closed, and terminates in a central handle or knob, d, immediately below which, and projecting into the cylinder, is the stud e, having a hole therein, through which is engaged the end h of the coilspring 7c, the other end of which terminates in a straighty wire, m,which passes Kdown through the oriiice or hole a in the central plug, B, into the enlargement b thereof', when a band or coil, n, is formed on the end of said wire to` retain the spring in place and hold the parts together when in place. To lill this cup with oil, the

operator lifts the cylinder C (the cup A being secured to place by means of its threaded plug B) until the openingsv c are disclosed above the upper end of the cup A, Wlienoil is poured through such openings until snch` cup is filled. On releasing the lifting force the contraction of the spring closes the cylinder C against the admission of air, the shoulder-flange o fitting closely upon the top of the cup A for that purpose. It will be seen that by this construction the cap of the oilcup never can be accidentally removed or lost, as the action of the spring is always to holditin place, and that the cap or inner cylinder may beturned around without danger of twisting off the spring. p

What I claim as my invention is- `l. An oil-cup consisting of two cylinders,

the one closely fitting inside the other and forming va cap thereto, such two cylinders bcing secured together by a coil-spring, one end Aof which is secured Vto one of the cylinders 'minating in a cup-shaped enlargement, b, a

perforated cylinder, C, fitting closely within such cup, and provided with a knob, d, and a'- stud, e, and a coil-spring, 7c, one end of which is secured to said stud e, and the other within the cup-shaped enlargement b in the stud B, the parts being constructed, combined, and operating as and for the purposes specified.
